Controlled formation of a variety of 3D structures was observed at high polymer weight fractions in water from a single diblock, consisting of poly( N ‐isopropylacrylamide), PNIPAM, and polystyrene, PSTY segments. The structures form through a mechanical process driven by swelling of hydrophilic polymer segments upon a change in temperature (see picture, SDS=sodium dodecylsulfate).
